Claude Code vs Gemini CLI: Is the Free Tier Still Worth It?

Most Claude Code vs Gemini CLI articles still say "Gemini CLI is free, Claude Code isn't." That was true in 2025. It isn't anymore for individual users, and it changes the whole comparison. Here's what each tool is today, who can still use Gemini CLI, and how they compare on cost, models and extensibility.

How we researched this: Google's announcement, the Gemini CLI GitHub repo and docs, Google's API pricing, and Anthropic's docs and pricing, all as of October 2026, plus public user reports. We haven't run our own benchmarks.

What happened to Gemini CLI's free tier?

Google is moving individual users from Gemini CLI to a new tool called Antigravity CLI. In a May 19, 2026 post on the Google Developers Blog, Google set the date: June 18, 2026. From then on, Gemini CLI and the Code Assist IDE extensions stopped serving Google AI Pro and Ultra subscribers and free Code Assist for individuals.

The Gemini CLI README now opens with the same notice: "Unpaid tier and Google One users: Gemini CLI was replaced by Antigravity CLI on June 18th, 2026."

Who can still use Gemini CLI, per Google's post:

• Companies on a Gemini Code Assist Standard or Enterprise license, or Code Assist for GitHub through Google Cloud ("your access remains unchanged").
• Anyone with a paid Gemini API key or a Gemini Enterprise Agent Platform API key.

One more caveat from the README: Gemini CLI "has not been optimized for Gemini 4 Argon," Google's newest model, and Google points users to Antigravity CLI for it. Google also says Antigravity CLI won't have one-to-one feature parity at launch, though Agent Skills, Hooks, Subagents and Extensions (now plugins) carry over.

So if you landed here looking for a free terminal agent from Google, the real comparison is now Claude Code vs Antigravity CLI. Our best free AI for coding roundup covers free options.

Claude Code vs Gemini CLI at a glance

How much does each cost?

Claude Code is a subscription; Gemini CLI is now mostly pay per token. Prices are as of October 2026.

Claude Code is included in every paid Claude plan, per claude.com/pricing. Pro is $20/month ($17 billed annually). Max starts at $100/month with 5x or 20x Pro's usage. Team Standard seats cost $25 monthly or $20 billed annually.

Usage is shared with Claude chat and resets on a rolling five-hour window, with weekly caps on paid plans.

You can also use an Anthropic API key, where Opus 5.5 costs $4 per million input tokens and $20 per million output. More detail is in our Claude Code pricing guide.

Gemini CLI is free to install, but individuals now need a paid Gemini API key. Standard paid rates from Google's Gemini API pricing page:

Those token prices are well below Claude Opus 5.5's list price. If you're happy with Flash-class models and run light workloads, a paid Gemini key can cost less than $20 a month. Heavy agent sessions send a lot of context on every turn, though, so a flat Claude plan is easier to budget for.

You may still see old quota numbers. Gemini CLI's own quota page still lists 1,000 requests a day for free Google sign-in. Google's announcement and the README notice say those accounts were moved to Antigravity CLI, so don't plan around that number.

Which has the better models?

This is the question everyone asks, and the answer shifts with every release. We haven't run our own tests, so we won't pick a winner on raw quality. What we can compare is what each tool gives you access to. Claude Code defaults to Opus 5.5 with a 1M-token context, per its model configuration docs.

Gemini CLI's model docs list Gemini 3 Pro Preview, Gemini 3 Flash Preview, Gemini 2.5 Pro and Gemini 2.5 Flash, with an Auto mode that routes by task complexity. Google's newest model, Gemini 4 Argon, is the one Google says the CLI isn't optimized for. In practice, Gemini CLI users are a generation behind Google's best model unless they move to Antigravity.

Older comparisons often say Gemini CLI wins on context (1M vs 200K). That gap has closed: Claude Code's current Fable, Opus, Sonnet and Haiku models all default to 1M tokens.

Extensibility: MCP, hooks, skills and extensions

Both tools are extensible, and on paper the feature lists are close.

Gemini CLI's docs cover hooks, extensions, MCP servers, Agent Skills, subagents (marked preview), sandboxing, checkpointing, GEMINI.md context files and a headless mode for scripts. The README adds custom commands, Trusted Folders and a VS Code companion. MCP servers go in ~/.gemini/settings.json.

Claude Code's overview lists MCP, CLAUDE.md with auto memory, skills, hooks, subagents and background agents, plus the Agent SDK for building your own. It also reaches past the terminal: Claude Code on the web, cloud scheduled tasks that run when your laptop is off, a Slack integration, GitHub Actions and GitLab CI/CD, and JetBrains and VS Code extensions.

The deciding factor is momentum. Google's post says its effort now goes into Antigravity, and that extensions move there as plugins. If you're building a long-term workflow, Claude Code's extension points have a clearer future than Gemini CLI's.

Downsides of each

Claude Code:

• No free tier; you need at least Pro at $20/month or an API key.
• Claude models only.
• Closed source.
• Usage limits are shared with regular Claude chat.

Gemini CLI:

• No longer serves free or Google One accounts.
• Not optimized for Gemini 4 Argon, Google's newest model.
• Google's new features are going into Antigravity CLI instead.
• Pay-per-token billing makes heavy use harder to predict.

Which should you choose?

• Choose Claude Code if you're an individual developer or small team that wants a well-supported terminal agent with a flat monthly price, strong Claude models and a 1M-token context. It's the safer long-term bet of the two.
• Choose Gemini CLI if your company already has a Gemini Code Assist Standard or Enterprise license, or you want an Apache-2.0 open-source agent and are happy paying Gemini API rates for Flash or 2.5 Pro.
• Look at Antigravity CLI instead if you wanted Gemini CLI for the free tier. That's where Google moved free users.

FAQ

Is Gemini CLI still free?

Not for most individuals. Since June 18, 2026, unpaid and Google One accounts are routed to Antigravity CLI. Gemini CLI itself is still free, open-source software, but you need a paid Gemini API key or an organization Code Assist license to run it.

Is Gemini CLI being shut down?

Not for everyone. Google says access stays the same for Code Assist Standard and Enterprise customers and for paid API keys, while individual and free users move to Antigravity CLI.

Does Claude Code have a free tier?

No. Claude Code is included in paid Claude plans starting with Pro at $20/month, or you can pay per token with an Anthropic API key.
